To make the Read More link bold, place this in your Custom CSS area in the Template Manager:

.readmore-link {font-weight:bold;}

In order to make the read more link show up after the paragraph you would have to create an override for the com_content display of an article. This page will walk you through it: https://docs.joomla.org/Understanding_Output_Overrides#Copying_or_Creating_Layout_Files

How about the code to make "Add new comment" bold as well?
Thanks,
KK

.comments-link {font-weight:bold;}
